PresentationThe MX 32 is a compact, low-profile controller that continuously monitors gas detection, including 4-20 mA, dry logic input, MODBUS RS485 signal from compatible detectors.

Controller

MX 32

Features

• Analog and digital controller

• Up to eight detectors

• Fully scalable

• SIL1 reliability

MX 32

Different modules can be connected to improve the capabilities of the controller.

Modules

4 or 8-relay module

16-logic-input module

Addressable module of 16 logic input for recovery of digital information such as fire or intrusion alarms, emergency stop, limit switch activation, etc.

8-analog-input

4-analog-output

Programmable 4 or 8--relay module can be located closer to the actuators for cost savings.

Can connect standard analog transmitters (gas or flame detectors for instance) on a digital line for cost savings.

Addressable 4-analog-output module that delivers four analog 4-20mA signal outputs (detector output copy, min, max,average of a group of detectors) for connection to a datalogger, a PLC, a Building Management System (BMS), etc.

Controller

MX 32

Five programmable events per detector

Smart keys make embedded multi-language

menus simple to use

5” LCD back-lit graphic display

MX 32 takes analog and digital inputs and covers all needs for a wide variety of applications.

The MX 32 digital technology allows up to eight detectors to be distributed on two lines for increased cost savings.

Lockable toggle latch

Four on-board relays and one fault relay

Power supply 100-240Vac (optional)

RS485 output (optional)
